Swift: imageWithData not available

Question

I am creating a UIImage object in swift by passing image data to it. Similar to how its done in objective-c

UIImage imageWithData

However, i see error that says: imageWithData is not available for swift.

What is the alternative for imageWithData for Swift ?

The methods `initWithX` become an initializer with a parameter of `x`. Thus, `initWithData:...` becomes`UIImage(data:...)`. — Rob, Mar 25 '15 at 18:44
Did you read the complete error message? My Xcode displays `error: 'imageWithData' is unavailable: use object construction 'UIImage(data:)'` — Martin R, Mar 25 '15 at 18:48

I can't find the imageWithData class method in the UIImage documentation, however you could use init(data:) data method:

let image:UIImage = UIImage(data:youDataHere);

When i print the album art image i extracted from an MP3 file. Its a series of hexadecimal numbers. Is that considered as NSData ? – Nick Mar 25 '15 at 19:28
Yes, NSData is a series of hex number. – Lord Zsolt Mar 25 '15 at 19:41
I figured it out, my image data was of string type. I returned it as NSData type and that worked – Nick Mar 28 '15 at 18:36
let image = UIImage(data:yourData!) could be better. – Hope Oct 21 '15 at 08:34
